Mercedes-Benz ha e lumele ho mafura a maiketsetso, empa e ntse e tsoela pele ho lumela lienjineng tsa diesel. Ntle le ho kenyelletsoa ha motlakase, mofuta oa Jeremane o ntse o tsoela pele ho tsetela molemong ona oa mollo ho hlabolla mehlala ea ona.
Ka hona, ka ho fihla ha Mercedes-Benz E-Class e nchafalitsoeng (moloko oa W213) 'marakeng - e ileng ea ntlafatsoa hanyane selemong sena - mofuta oa "vitaminized" oa enjene ea diesel e seng e tsebahala ea OM 654 (220 d) e tla hape fihla.
E thehiloe ka 2016, enjene ena ea 2.0-litre, four-cylinder, aluminium blocks e se e ntse e tsoela pele ho iphetola. OM 654 M.
Ke eng e Ncha ho OM 654 M
Block e tšoana le OM 654, empa li-peripherals li fapane. Hona joale OM 654 M e fana ka matla a 265 hp kgahlanong le 194 hp ya moloko wa pele (e tla tswelapele ho ba teng ka hara mefuta ya E-Class) e e behang e le disele e matla ka ho fetisisa ya disilindara tse nne lefatsheng.Liphetolelo tsa animated tse nang le enjene ea OM 654 M li tla rekisoa ka 300 d acronym.
Ho eketsa matla ka ho feta 70 hp, ho tloha bolokong bo nang le matla a lilithara tse 2.0 le li-cylinders tse 'ne, liphetoho tse sebelisoang ho OM 654 li ne li tebile:
- Crankshaft e ncha e nang le stroke e phahameng (94 mm) e bakang keketseho ea ho falla ho 1993 cm3 - pele ho 92.3 mm le 1950 cm3;
- Khatello ea ente e ile ea phahama ho tloha ho 2500 ho ea ho 2700 bar (+200);
- Li-turbo tsa geometry tse peli tse pholileng ka metsi;
- Li-plungers tse nang le kalafo e thibelang khohlano ea Nanoslide le likhoele tse ka hare tse tlatsitsoeng ka motsoako oa sodium (Na).
Joalo ka ha ba bangata ba tla tseba, sodium (Na) ke e 'ngoe ea litšepe tse sebelisoang haholo lits'ebetsong tsa sehatsetsing sa limela tsa matla a nyutlelie ka lebaka la litšobotsi tsa eona: botsitso le matla a ho qhala mocheso. Ka hare ho OM 654 M tšepe ena ea metsi e tla ba le ts'ebetso e ts'oanang: ho thibela motlakase hore o se ke oa chesa haholo, o fokotsa likhohlano le ho roala ha mechine.
Ntle le li-turbos tse pholileng ka metsi, li-piston tse nang le li-ducts tse ka hare tse nang le sodium alloy (Na) ke e 'ngoe ea tharollo e bohlale ka ho fetisisa e teng ho OM 654 M. Empa ha se bona feela…
Ho batla ho tlama motlakase
Ho phaella lintlheng tsena tse ncha, OM 654 M e boetse e na le thuso ea bohlokoa: tsamaiso e bonolo-hybrid 48 V. Theknoloji eo nakong e tlang e seng e le hōle haholo e lokela ho ba teng lienjiniking tsohle.
Ke sistimi ea motlakase e ts'oanang e nang le jenereithara / starter le betri, e nang le mesebetsi e 'meli ea bohlokoa:
- Hlahisa matla a ho matlafatsa tsamaiso ea motlakase ea koloi (moea oa moea, tsamaiso, tsamaiso ea ts'ehetso ea ho khanna) ho lokolla mochine o tukang ho tloha mosebetsing ona, kahoo o eketsa matla a eona a matla;
- Thusa enjene ea mollo ho potlakisa, e fana ka keketseho ea nakoana ea matla a ho fihla ho 15 kW le 180 Nm ea torque e phahameng. Mercedes-Benz e bitsa mosebetsi ona EQ Boost.
Hape lebaleng la ho loants'a mesi, ho ile ha boela ha etsoa mosebetsi o matla oa ho phekola likhase tse tsoang ho OM 654 M.
Hona joale enjene ena e sebelisa mochine o motlakase oa boemo bo botle (o nang le phekolo ea holim'a metsi ho fokotsa li-deminerale tsa NOx) le tsamaiso e mengata ea SCR (Selective Catalytic Reduction) e kenyang Adblue (32.5% urea e hloekileng, 67.5% ea metsi a demineralised) ho mokhoa oa ho ntša metsi ho fetola NOx (nitrogen oxides) hore e be naetrojene le metsi (mouoane).
Re ka lebella eng ho 300d?
Ha e fihla 'marakeng, OM 654 M e tla tsebahala ka 300 d - ke seo re tla se fumana ka morao ho mefuta eohle ea Mercedes-Benz e nang le enjene ena.
Re sebelisa mohlala oa Mercedes-Benz E-Class e tla qala enjene ena ea 300 d, re ka lebella litšoantšiso tse khahlisang haholo. Phetolelong ea 220 d mohlala ona o se o ntse o khona ho potlakisa ho tloha 0-100 km / h ka metsotsoana e 7.4, 'me o fihla lebelo le leholo la 242 km / h.
Ka hona, ho ka lebelloa hore 300 d ena - e tla ba diesel e matla ka ho fetisisa ea li-cylinder tse 'nè lefatšeng - e tla khona ho felisa litekanyetso tsena. Ka matla a fetang 265 hp le torque e lokelang ho feta 650 Nm (EQ Boost mode) Mercedes-Benz E 300 d e lokela ho khona ho phethahatsa 0-100 km / h ka metsotsoana e 6.5 le ho feta 260 km / h lebelo le phahameng. ntle le moeli oa elektroniki).
A na u ka thabela ho tseba lintlha tse ling ka enjene ee?
